Primary structure and expression of a product from cut, a locus involved in specifying sensory organ identity in Drosophila

Abstract
In the absence of cut gene activity in Drosophila, external sensory organs are transformed into chordotonal organs. Here we show that the cut locus encodes a large protein containing a homoeodomain and is expressed in nuclei of cells in external sensory organs but not in cells within chordotonal organs.
